Abstract:
An apparatus for redundancy of a memory array includes a primary memory array including a plurality of memory cells, one or more of which are defective. A redundant array includes a CAM array that includes a plurality of memory cells. The CAM array is addressed by the address of a defective memory location within the primary memory array and provides a match identification and a resource identification. The redundant array also includes a translation array wherein an offset to configure an input/output multiplexer is stored. The redundant array also includes a redundant data array including a plurality of memory cells wherein one or more memory cells of the redundant data array are used instead of one or more defective memory cells of the primary array.
